Trying To Find Some Change Gears FOUND

[Sniperhandle]

I am trying to find some change gears, Thought I might post it in this section too,
I am looking for change gears for an Asian Lathe, It is a 1340 lathe, The gears are most likely the same for a whole lot of them regardless of the Name Plate.
The bore diameter is right at 19.00 mm or 0.748 approximately. They have a step on one side as shown in these pics. I am looking for these tooth count gears:
60T
56T
54T
57T
69T
78T
30T
66T
Look through your stuff for me please?

You’d do better to figure out the gear pitch/ module as that’s what important
Bores can be sleeved or bored out

Might could find some gear blanks and bore them out too

Grizzly has one gear for it, The 60 tooth, I am going to order that one if the lady at Knuth can't help me. She is checking with the Factory, They don't have them here in the states. Thanks Gene!

I bought a Mill and this machine kind of jumped on the trailer with it!

That lathe above has a quick change gear box, why would you need that many change gears? Metric? For the price of that many change gears, you could build and install an Clough42 electronic lead screw and never have to change gears. I've got a PM-1340GT but the gears are 18mm shaft.

Unfortunately, If you were going to thread a rem 16 TPI and then flip it around and thread the muzzle 1/2-28 you would have to change the "B' gear.

It has a 60T on "A" and a 63T on "B" and 120/127 gear with the 120 being used, I set it up for a 14 TPI thread and it cut a perfect thread, Which makes sense according to the chart, If I try 16TPI it just wipes out the thread. I haven't run into a lathe that works like this before. I could get a large number of imperial threads off of the factory installed gear train on most other lathes I have used, But this lathe is supposedly Asian sourced parts and assembled in Germany.

The main thing I liked about it was it came from the factory with a 3 axis DRO, So it also has one on the compound.

Then you're just about set up to cut your own gears!

Clough42 electronic lead screw

^^^ Do this

I already had a mill and a dividing head BUT, now I have 2.

Maybe? I have looked at some guys projects doing that, The gears would be cheaper if you add up all the time involved.

Boston gear & martin useful to stock change gears.

The gears for my PM 1440 are that bore size. Maybe check with PM?

By strange coincidence, I just made my first spur gear today.

Very cool Gene!
